Another tweet shows Nikiforov responding to a retweet that suggested the same notion as the AP's news.

Of course, that doesn't mean Facebook isn't interested in investing more in its presence in the country.

"Russia has a strong developer community that has been making great use of the Facebook platform," according to a statement from Facebook. "A number of gaming companies in particular are building their businesses in Russia thanks to the global audience they reach through Facebook."

Facebook said Zuckerberg is spending several days in Moscow, where he will "attend a number of private functions as well as public engagements," including a talk for students at Moscow State University and a visit to the Facebook Moscow Hack -- a part of the World Hack 2012 tour.
